A tank at America’s most contaminated nuclear site is leaking radioactive liquids, raising concerns about the integrity of other storage facilities at the Hanford Nuclear Reservation in Washington state.

Officials say the single-shell tank could be leaking up to 1,135 liters per year, creating a long-term threat that could impact groundwater or rivers.

Washington state Governor Jay Inslee said Friday, “we were told this problem was dealt with years ago.”

A cleanup of the site would cost billions of dollars and last decades.
